Preheat oven to 400F degrees.
Lightly grease 2 baking sheets with cooking spray and set aside.
In a large mixing bowl combine, potatoes, olive oil, chili powder, cayenne pepper, ground cumin, corn starch, salt and pepper. Toss to combine.
Add lime juice and mix until thoroughly incorporated.
Arrange potato slices on prepared baking sheets. You will have to bake in batches.
Bake for 15 minutes; remove from oven and turn over the potato slices.
Put back in the oven and continue to bake for 10 minutes, or until potato chips begin to curl up on the sides.
Remove from oven and let stand 1 minute.
Transfer chips to a wire rack; let stand 5 minutes.
If desired, taste for seasonings and adjust accordingly.
Repeat with the second batch.
